SHABPENINZ DEVICE FOR RAZOR-BLADES.

Specification of Letters Patent.

- Patented May 24, 1921.

Application filed May 28, 1919. Serial No. 800,397.

following is a full, clear, and exact description, such as willenableothers skilled in the art to which it pertains to make, construct, anduse the same, referencebeing had to the accompanying drawings, and tonumerals of reference marked thereon, forming a part of'thisspecification.

The object of my invention is the production of asharpening device forsafety razor blades, which shall'be simple and effective inconstruction, comparatively inexpensive in cost, and rovided withsecuring means to engage wit corresponding means formed on a stroppingdevice whereby the said sharpening device can be readily andconveniently secured to or removed from the stroppin device, in orderthat the cutting edge of t e blade may be sharpened without removing theblade from the stropping device. I

With this end in view, my invention con sists in certain novelties ofconstruction and arrangements of parts, as hereinafter set forth andpointed out in the claims.

In the accompanying drawings,

Figure 1 represents, a side elevation of my improved sharpening device.

Fig. 2 represents, a front elevation of the same.

Fig. 3 represents, a rear elevation of the same.

Fig. 4 represents, a side elevation of a razor stropping device, insection, showing my improved sharpening device secured thereto and inoperative position, and

Fig. 5 represents, a front elevation of thestropping device, a portionof the handle being broken away.

Similar numerals of reference refer to like parts throughoutthespecification and draw- I he razor stropping device illustrated inthe accompanying. drawings, (forms the subject matter of atentapplication, Serial No. 280,982,,filed arch 6, 1919) is provided withreceiving means to engage with corresponding recelving means formed onthe sharpening device, whereby said device can be readily andconveniently secured to or removed from the stroppin device, in orderthat the cutting edge of t e blade may be sharpened without removing theblade from the stropper.

The said razor stropping device comprises a frame adapted to slidelongitudinally of a strop, said frame comprising a body portion 1 andtwo opposite end ortions 2-2 parallel each to each. A han le 3 isivotally connected to the frame for permitting movement of the framerelative to the handle, and a blade holder 4: is rotatively connected tothe said side portions of the frame. roller 5 is also connected to saids1de port1ons of the frame, and means are carried by said roller fortransmitting rotary movement to said blade holder.

. The body or frame of my improved stroppmg devlce may be stamped from;sheet metal or the llke, and afterward bent into the desired shape .asshown.

The front and rear longitudinal edges 66, of the body or frame arepreferably bent upwardly to present bearing or guiding surfaces of thestrop.

hese bearing or guiding surfaces 66 are provided with receiving meanswhich as illustrated are alined openings 77 formed near the sideportions of the frame to en gage with the receiving means formed onbracket 10 and has secured thereto the gear 17 designed to mesh with agear 18 secured to the rod 9 and which serves to impart rotary motion tothe roller.

The bracket 10 in which said honing or abrading roller is journaled maybe stamped from sheet metal or the like and afterward bent into thedesired shape as shown.

The lower edge of the bracket is provided with two parallel andoutwardly extending tongues 12-12, designed to be received in the alinedopenings 77, formed in the front and rear longitudinal edges 6-*6, ofthe body or frame of the stropping device, properly positioning thesharpening device.

is also journaled in one of the arms of the are the side portions of abracket 14 which may also be stamped from sheet metal or the like andafterward bent into the desired shape as shown.

To the inner surface of said bracket 14 in any desired or convenientmanner, preferably by means of the plus 15--15, 1s secured a curvedspring 16 extending lengthwise thereof. a v

This spring 16 is preferably made from asingle piece of suitablematerial bent upon itself as clearly shown and designed to bear upon oneside of the razor blade so that the required degree of pressure can beexerted against the blade by pressing the pivoted bracket 14, by meansof the operators fingers, toward the roller 8.

To operate my sharpening device, 1t 1s only necessary to insert theintegral tongues 12-12 of the bracket 10, intothe almed slots 7-7, inthe body portion 1 of the razor stropping frame, thereby pos1t1on1ng thesharpening device, and then causin the curved end of the spring tongue13 o the bracket 10 to snap over one of the longitudinal edges 6, inorder to lock the sharp ening device to the frame of the stroppingdevice.

The pivoted bracket 14 is then in the position indicated in Fig. 4 ofthe draw-- ungs with the longitudinally arranged sharpening operation.

spring 16 bearing against the razor blade 19.

By pressing against the bracket 1 1 with the spring 16 bearing againstthe razor blade 19 the desired degree of pressure can be exerted againstthe blade during the Rotation of the roller by means of the handle willsharpen and polish the edge of the blade.

In order to remove the device from the frame, it only becomes necessaryto disengage the spring tongue 13 from the longitudinal edge 6 andcausin the tongues 12-12 to become disengaged rom the openings 7--7. v

I am aware that changes may be made in the several arrangements of thevarious parts, as well as in the details of construc tion thereof,without departing from the scope of my present invention; hence I do notwish to be limited to thearrangements and combinations of parts asherein shown and described, as obviousmodifications will suggestthemselves to those skilled in the art.

I claim.

1. A device for sharpening razor blades, comprising a frame made from asingle piece of suitable material, the lower portlon of said frame beingprovided with integral means for securing said device to a frame carring a razor blade holder, the upper portion of said frame being providedwith integral brackets for supporting a roller, a sharpening rollerrotatably mounted in said supporting brackets, a handle journaled in oneof the roller supporting brackets, means carried by the handle androller for transmittin rotary movement to said sharpening ro ler, andmeans to press a blade in said holder against said roller.

2. A device for sharpening razor blades,

comprising a frame made from a single piece of suitable material, thelower portion of said frame being provided with integral means forsecuring said device to a frame carrying a razor blade holder, the upperportion of said frame being provided with integral brackets forsupporting a roller, a sharpenin roller rotatably mounted in saidsupporting brackets, a bracket pivotally securedto the outer portions ofthe roller supporting brackets, a spring secured to and extendinglengthwise of said pivoted bracket and located in close proximity to thesaid roller, and adapted to bear upon the razor blade, a handle, meanscarried by the handle and roller for transmittin rotary movement to saidsharpening rol er.
